XTERRA is a series of cross triathlon races, i.e. three-sport races which include swimming, mountain biking, and trail running. The XTERRA Global Tour is owned and produced by XTERRA Sports Limited. The XTERRA race series is the best-known series of cross triathlons, and is considered by most to be the de facto world championship of the sport.[citation needed]
It began in 1996 on the Hawaiian island of Maui as the Aquaterra, and was later renamed the XTERRA. Japanese automaker Nissan licensed the name from the triathlon series for their own 1999-2015 sport utility vehicle — and was the race series' primary sponsor from 1998 to 2006, when the two companies parted ways.[1]
